This has taken much longer than expected, as backups at the Machine shop and at the platers kept me in limbo, but now I have the Beta Test piece done.....
Andial was getting $700 for this back then. Cost for this one is about 1/2.
This should also work as a frequency valve replacement, and we should have one for the 911 SC configuration soon.
Please email me, len.cummings at verizon.net if interested.
Thanks for looking.
